Method Detail

getOrientation

public char getOrientation()

returns the orientation of a curve

Returns:

curve orientation ('+'|'-')

setOrientation

public void setOrientation(char orientation)
                    throws GM_Exception

sets the curves orientation

Parameters:

orientation - orientation of the curve ('+'|'-')

Throws:

GM_Exception - will be thrown if orientation is invalid
